This book collates past and current research on one of the most promising emerging modalities for breast cancer detection. Readers will discover how, as a standalone technology or in conjunction with another modality, microwave imaging has the potential to provide reliable, safe and comfortable breast exams at low cost. Current breast imaging modalities include X- ray, Ultrasound, Magnetic Resonance Imaging, and Positron Emission Tomography. Each of these methods suffers from limitations, including poor sensitivity or specificity, high cost, patient discomfort, and exposure to potentially harmful ionising radiation. Microwave breast imaging is based on a contrast in the dielectric properties of breast tissue that exists at microwave frequencies.The book begins by considering the anatomy and dielectric properties of the breast, contrasting historical and recent studies. Next, radar-based breast imaging algorithms are discussed, encompassing both early-stage artefact removal, and data independent and adaptive beamforming algorithms. In a similar fashion, microwave tomographic reconstruction algorithms are reviewed in the following chapter, introducing the reader to both the fundamental and more advanced algorithms. Apart from imaging, the book also reviews research efforts in extracting clinically useful information from the Radar Target Signature of breast tumours, which is used to classify tumours as either benign or malignant. Finally, the book concludes by describing the current state of the art in terms of prototype microwave breast imaging systems, with a particular emphasis on those which have progressed to the clinical evaluation stage.This work is motivated by the fact that breast cancer is one of the leading causes of death amongst women in Europe and the US, and the second most common cancer in the world today. Such an important area of research will appeal to many scholars and practitioners.p>

Reviews the state of the art of a promising method for breast imaging Offers insight into the use of ultra-wideband techniques for the classification of benign and malignant lesions Outlines microwave tomographic methods for estimating the breast's complex permittivity Provides an overview of existing breast imaging prototype systems

Johan Jacob Mohr's research has spanned a broad range of electromagnetic sensing technologies ranging from air- and satellite borne synthetic aperture radar interferometry for measurement of glacier dynamics, over lidar for wind sensing to microwave imaging for medical applications. He received his PhD in 1997 from the Technical University of Denmark (DTU), and was at an internship at the Radar Science and Engineering group at the Jet Propulsion Laboratory in 1994-95. He continued at DTU as assistant and associate professor with projects on interferometric synthetic aperture radar. In 2006, he received a university position at DTU, where he gradually changed focus to the development of a second-generation 3-D microwave tomography system for breast cancer detection suitable for clinical test. Included was improvement of data acquisition accuracy, methods for prediction of the accuracy of the resulting images and utilization of multiple frequencies. Additionally, he supervised a wide range of bachelor and masters with Danish industry. In 2015, he joined Mellanox Technologies as Principal Engineer and is now working on system design and signal integrity.

Martin O'Halloran is a European Research Council (ERC) Fellow and Science Foundation Ireland Principal Investigator at the National University of Ireland Galway. His research interests span low-frequency and high-frequency electromagnetic imaging, radiofrequency hyperthermia and ablation, and the dielectric properties of biological tissue. He holds a PhD in Electrical and Electronic Engineering, and Master's degrees in both Academic Practice, and Clinical Research from the National University of Ireland Galway (NUIG). He has over 20 national and international research awards, and only last year (2014) was awarded Engineers Ireland's Chartered Engineer of the Year and NUIG's Early Stage Researcher of the Year for his work on medical device development. In the period from 2011-2015, he secured over 4.5 million in direct research and commercialization funding, and is technical-collaborator in two start-up medical device companies at NUIG. He has over 30 peer reviewed journal papers, and a similar number of international conference papers. He is also Vice-Chair of the MiMed COST Action (TD1301).
